Interesting. What do you like about code review things? I personally found it to be lacking. It's hard to dig up comments on branches that have been merged into a master branch and I'd also like to have notes/comments on the HEAD of a project. Right now, they just get perpetually buried. That's where a lot of project decisions end up getting made in my team.

Perhaps we should be using a wiki or some other system, but I'd really love for some more enhancements to code review.
